BLOOD & BLOOD TESTING
BLOOD CELLS
Erythrocyte (RBC)
Stacking allows for passage through narrow blood vessels
Leukocyte (WBC)
Have a nucleusFight disease
NeutrophilsEosinophilsBasophilsMonocytes/MacrophageLymphocyte
Granulocyte
This is a cell that shows granules (spots) after stainingNeutrophilsEosinophilsBasophils
WBC Granulocyte: Neutrophil
WBC Granulocyte: Eosinophil
Appears darker or more red than neutrophils due to larger granules
WBC Granulocyte: Basophil
Agranulocyte
This is a cell without granulesMonocytes /MacrophagesLymphocytes
WBC Agranulocyte: Monocyte (Macrophage)
Nucleus can appear as several different shapes- Remember: No granules make cytoplasm much lighter
than granulated WBC
WBC Agranulocyte: Lymphocyte
Relatively similar size as RBCVery little cytoplasm visible due to size of nucleus
Platelets (Thrombocytes)
Platelets can appear in clusters or singular

Hematocrit – Packed cell volume (PCV)
Percentage of erythrocytes in the blood
Differential White Blood Cell Count (DIFF)
A test where the first 100 WBCs are categorized according to type.
This number can then be compared to normal % to determine type of illness.
WBC DIFF
Tallquist hemoglobin test
Measures the amount of hemoglobin in the blood to help determine anemia
Blood Typing
Antigens
Located on the erythrocytesDetermines blood type
Antigen Antigen
Antigens No Antigens
Antibodies
Identifies a specific antigen located on the erythrocytes
Agglutination
Clumping that occurs when antibodies join to antigens
ABO system
Rh antigen
